introduction and aims: omeprazole is a gastric parietal cells proton pump inhibitor that is also active against h. pylori in vitro. this study was designed to examine the neutralization of h. pylori cytotoxicity on vero cells by omeprazole micronized in strains isolated from gastritis, ulcer, cancer and barrett's ulcer, to determine whether omeprazole can inhibit vacuolation of the vero cells i...

Thermal conductivity of superconducting MgB 2 was studied in both the superconducting and the normal state region. The latter is almost equally determined by the electronic-and the lattice contribution to the total thermal conductivity. In the superconducting state, however, the lattice contribution is larger. The electronic thermal conductivity below T c was derived from the experimental data ...

Antifreeze protein (AFP) types, I, II and III were tested for their ability to protect red blood cells from lysis during warming, after cryopreservation in hydroxyethyl starch. All three types reduced hemolysis to 25% of control values at similar micromolar concentrations but enhanced lysis as the AFP concentration approached millimolar levels. Site-directed mutants of type III AFP with differe...

The effect of rotation on turbulent convective flow between parallel plates has been assessed with direct numerical simulations. With increasing rotation-rate an interesting transition is observed in the vertical-velocity skewness. This transition indicates a localization of motion directed away from the wall and correlates well with changes observed in the heat flux, as well as in the thermal ...

The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simultaneously using transient plane source technique. The temperature dependence of thermal transport properties is studied in the temperature range 83-303 K. Different relations for the estimation of thermal conductivity are also tested. T...

background: the purpose of this study was to investigate the enhanced thermal resistance mechanism of the du145 tumor spheroid cultures as compared to the prostate carcinoma cell line's monolayer cultures. materials and methods: du145 cells were cultured either as spheroids or monolayers. cultures were treated with hyperthermia in a precision water bath (at 43°c for 60 minutes) and/or quercetin...

Front Cover: In article 2300008 by Dhruba J. Haloi and co-workers, chitosan/kaolin clay biocomposite films are prepared mixing an aqueous acidic solution of chitosan with various amounts kaolin followed casting them in a petri dish. These exhibit better mechanical thermal properties good water absorption capacity. significant inhibition for the growth gram-negative bacteria.

Alpha-amylase is widely used as an industrial enzyme, and a therapeutic target for which inhibitors are designed. Organic solvents are used to dissolve various compounds that would be studied as moderators of alpha-amylases, but they could themselves affect enzyme activity and stability. Methanol, ethanol and propanol are simple alcohols that may be commonly used to this end, and their effect h...
